Abstract

Degenerative processes in the central nervous system contribute to in cognitive function decline in the elderly. Physical exercise may prevent this decline. However, elderly people often require modified forms of activity to ensure both safety and effectiveness. This study aimed to investigate the the effect of chair-based exercise (CBE) on cognitive function in elderly people. This study was conducted a two nursing homes using a two-group pretest and posttest experimental design with a control group. All participants were informed about the procedures of study, provided written informed consent, and underwent an initial cognitive assessment using the mini-mental state examination (MMSE). Participants in the intervention group engaged in CBE sessions over a four-week period. Following the intervention, cognitive function was reassessed in both groups. The Wilcoxon signed-rank test was used to analyze within-group changes, while independent t-tests were used to assess between-group differences in cognitive function scores. A significant improvement in cognitive function was observed in the intervention group after the four-week CBE program (p = 0.008). Moreover, a significant between-group difference in cognitive score changes was found (p = 0.003), favoring the intervention group. In conclusion, a four-week CBE program significantly improved cognitive function among elderly participants. These findings support the use of CBE as an accessible and effective intervention to promote cognitive health in elderly people.

Abstract

Acne vulgaris is a skin disease caused by chronic inflammation in the pilosebaceous unit, which produces sebum. The factors causing acne vulgaris are multifactorial and interact with each other. Medical students are a subgroup of society who are vulnerable to experiencing sleep disorders. Therefore, this study aims to explore the relationship between acne and sex, sleep quality, and skin type, especially in medical students. This research uses survey methods and analytical observation with a cross-sectional approach. The sampling technique is stratified random sampling. Validated questionnaires were used to assess sleep quality and skin type. Univariate analysis showed that of the 85 participants, the majority were female and aged 20 years. The prevalence of acne in this study was 52.9%. Most respondents had poor sleep quality (63.5%) and oily skin (69.4%). Based on bivariate analysis, acne vulgaris was significantly related to sleep quality (p=0.046) and skin type (p=0.025). Multivariate analysis showed that skin type had the most robust relationship with acne vulgaris (OR = 2.876; 95% CI = 1.077-7.685).
